  <div>
   <p>This section describes how to restore disks of a VM that has been backed up to the original VM or a new VM.</p>
   <div class="section">
    <h4 class="sectiontitle">Context</h4>
    <p>The <span>product</span> allows you to restore disks to the original or a new VM using backup copies, replication copies (restoration to the original VM is not supported), copies generated by live mount, or imported copies. When using a copy generated by live mount, ensure that the copy has been unmounted from the VM.</p>
    <ul>
     <li>Restoring disks to the original VM<p>When disk data is restored to the original VM, if a disk exists in the corresponding slot of the original VM, the data on the disk will be replaced. If the original disk still exists in the corresponding slot of the original VM, incremental restoration is performed. (Incremental restoration is performed only when the latest backup copy is used for restoration for the first time. In other cases, full restoration is performed). If no disk exists in the corresponding slot of the original VM, full restoration is performed. That is, a disk is created for restoration and then mounted to the corresponding slot.</p></li>
     <li>Restoring disks to a new VM<p>When disk data is restored to a new VM, if a disk exists in the corresponding slot of the specified new VM, the data on the disk will be replaced. If no disk exists in the corresponding slot of the new VM, full restoration is performed. That is, a disk is created for restoration and then mounted to the corresponding slot.</p></li>
